** only if the least significant byte of P1 is 0x01.

** If this byte is 0x00, and one of the values being compared is numeric
** and the other text, an attempt is made to convert the text value to 
** a numeric form.

** If the second least significant byte of P1 is not 0x00, then it must
** be an affinity character - 'n', 't', 'i' or 'o'. In this case an 
** attempt is made to coerce both values according to the affinity before
** the comparison is made.
**
** Once any conversions have taken place, and neither value is NULL, 
** the values are compared. If both values are blobs, or both are text,
** then memcmp() is used to determine the results of the comparison. If
** both values are numeric, then a numeric comparison is used. If the



** two values are of different types, then they are inequal.
